Described herein is a system for reducing vibration of a lens. One way to reduce vibration is through a programmable processor configured to divide a lens movement requirement into smaller lens movements and then insert a wait time after completing the smaller lens movements. The smaller lens movements can be repeated for subsequent smaller lens movements until all the remaining smaller lens movements have been completed. The system may include an actuator configured to move the lens; and wherein the lens movements are completed within a processing time of one image frame.

System for reducing lens vibration

In a method for reducing lens vibration in an image capture device, a lens movement requirement is broken up into N smaller lens move steps, and the lens is moved a first of the N smaller steps. A wait time is inserted after completing the first of the N smaller steps, and then the moving and inserting steps are repeated until the remaining N smaller move steps have been completed. The image capture device includes a voice coil motor for moving the lens under control of a controller in accordance with the lens movement requirement, which reflects a determined lens position. The voice coil motor includes springs which impart vibration to the lens during lens movement. The vibration imparted by the springs to the lens is thus actively dampened during the lens movement to the determined lens position.
